HANDLING DEVICES (1) Preventing Latch-up

A latch-up can occur if, on this device, (a) a voltage higher than power supply voltage or a voltage lower thanGND is applied to an input or output pin or (b) a voltage higher than the rating is applied between power supplyand GND pins. The latch-up may cause components to burn out because the power supply current increasessignificantly. Make sure that the maximum ratings are not exceeded while the device is being used.

(2) Handling unused pins

Leaving unused input pins unconnected may cause a malfunction. Handle unused pins by connecting to a pull-up or pull-down resistor.

(3) Power supply pins

Ensure that the impedance of the connection from the power supply source to the power supply pins on thedevice is as low as possible.

It is recommended that a ceramic capacitor of approx. 0.01 µF and an electrolytic capacitor of approx. 10 µFare connected in parallel between the power supply pins and ground pins as near to the device as possible toact as bypass capacitors.

(4) Crystal oscillator circuit

Noise near the XIN and XOUT pins may cause the device to malfunction. Design the printed circuit so that thewiring between the crystal oscillator and the XIN and XOUT pins does not cross over any other wiring as muchas possible. It is strongly recommended that the circuit board artwork is designed such that the XIN and XOUTpins are surrounded by ground plane for more stable operation.

OSCILLATION FREQUENCYThe frequencies of the PLL1, PLL2, PLL3, and SSCG can be determined by the following formula.

Note : From among the range of frequencies that can be selected by the above formula, the range of frequencies that can actually be generated is from 128 MHz to 400 MHz.

M and N can be configured separately for each of the PLL1, PLL2, PLL3, and SSCG. Furthermore, these canbe configured separately for each of the SL0, SL1 pin settings.

MODULATION INDEX AND MODULATION PERIODThe SSCG is able to output the clock which is applied spectrum modulation. The modulation index is selectablefrom OFF, ± 0.5%, ± 1.0%, ± 1.5%, and ± 2.0%, and can be changed independently for each of the SL0 andSL1 pin settings.

The period of modulation can be determined from the following equation.

Note : The value of L is fixed by mask option.It can not be changed according to the SL0 or SL1 pin setting.

Oscillation frequency = M

OUTPUT FREQUENCYThe output pins can output the reference clock, or the clocks SSCG, PLL1, PLL2, or PLL3 frequency divided by2 to 16 (they can not output by dividing the reference clock). Pins which do not need the clock output can beconfigured as fixed “L” outputs or as Hi-Z. The frequency division ratio can be configured by mask option andby setting SL0 and SL1 pins.

The clock sources that can be selected for each of the clock outputs are as shown in the following table.

: Enable, : Disable

Note : Set by mask option.

POWER DOWNXPD = “H” : Normal operating mode

XPD = “L” : Power-down mode. Clock outputs (CLK pins) are set to “L” or Hi-Z.

Note : If the XPD pin is set to “L”, all of the PLL oscillator circuits are stopped and are placed in the power-down state, and the device enters a low-power consumption mode. In the power-down state, the clock output pins CLK1 to CLK3 and CLK5 to CLK9 output “L” or are placed in the Hi-Z state.The output pin state during power-down is fixed by mask option.The SL0, SL1 pin settings do not enable to switch the fixed states between “L” and “Hi-Z”.

LOCK-UP TIMEThe clock outputs from the CLK1 to CLK3 and CLK5 to CLK9 pins conform to the ratings after the lock-up time(tLK) has elapsed after the states of all of the power supply, input clock, and pin settings have stabilized. Theoutput frequency, output clock duty cycle, modulation period, and cycle-cycle jitter are not guaranteed duringthe lock-up period. It is therefore recommended that processing, such as releasing device reset, is performeduntil after the lock-up time has elapsed.

Check the characteristics of the oscillator or clock being used for the stabilization wait time of the input clock. Ifthe built-in oscillator circuit is used, the stabilization wait time depends on the characteristics of the oscillator.

<At power-on>

The input clock oscillation stabilization wait time is required when the power is turned on.

When the XPD pin is fixed at “H”, the desired clock can be obtained after a maximum of the stabilization waittime of the clock being input to XIN plus the lock-up time (tLK) has elapsed.

<On release from power-down when using clock input>

When the power down is controlled by the XPD pin, the desired clock is obtained after the pin is set to “H” leveluntil the maximum lock-up time tLK has elapsed.

<On release from power-down when using an oscillator circuit>

When the XPD pin is set to an “L” level, the device enters power-down mode, and oscillator on the XIN andXOUT pins is stopped in order to stop the internal oscillator circuit of the device.

When the XPD pin is set to the “H” level and the device changes to normal operating mode, the oscillator circuitbegins operating and the XIN and XOUT oscillator is started. However, a prescribed time is required until theinput clock becomes stable (the stabilization wait time). Furthermore, because the lock-up time is required beforethe output clock stabilizes, the maximum amount of time from when the power-down is released until the outputclock stabilizes is [oscillator stabilization time] + [lock-up time].
